Can I Concatenate the lines with the same line# from 2 different files

[kobewins]

Hi,

I need to concatenate the lines with the same line# from 2 different file(as following). The Output_File is what I would like to have. How I do it?

Thanks
David

otherThing --> 222C
Nothing --> 321C

Output_File

2 Thething --> 234B...
3 otherThing --> 222C

See if you have "paste".

$ cat file1
1
2
3
4
$ cat file2
Something
SomethingElse
More Stuff
Enought
$ paste file1 file2 >file3
$ cat file3
1       Something
2       SomethingElse
3       More Stuff
4       Enought

You can modify the paste behavior to use something besides a TAB to link the lines together.

paste -d' ' FileA FileB >Output_File

Also have a look at the man page for paste.
